All locks now failed including ignition and will have to be replaced. Can you help identify what and where are the relevant serial numbers on the ECU and ignition so that replacement locks can be purchased. There are lock sets available on e bay but they do not say categorically that they fit a Jazz,i.e. MAY fit Jazz civic accord. They have identity numbers on like A10 or A50 etc. How do they correspond ?

Might be better to look at the official Honda website since that model is not sold in the US. Might find someone here, but wherever you are located is probably better.
